How Installing Energy-Efficient Windows in South Beloit Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that number, which helps you save some money on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 449 pounds per year on average.
Estimated Cost of Window Replacement in South Beloit
Let's go over the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Even though the national average of replacing a single window is about $600, it can range anywhere from $200 to $1,200. This is due to the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your South Beloit home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that influences the overall cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installer should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in South Beloit
In our search to make your home improvements easier and more eco-friendly in South Beloit, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we assessed several window installers in South Beloit and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve South Beloit so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to South Beloit's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of South Beloit window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

The national average cost of installing a window is about $600 but can range between $200 and $1,200, based on several factors.
